Nestled in the heart of Kinshasa, Congo, Sadiki Metals stands as a dedicated manufacturer and supplier, deeply connected to the region’s rich mineral heritage. We take immense pride in producing superior Copper Nickel 9010 forgings, components forged with precision and resilience. Our commitment is to deliver not just metal, but reliable solutions that meet the demanding challenges of modern industry, supporting both local growth and international projects with unwavering quality and expertise.
This particular alloy, often called 90-10 cupronickel, is a remarkable blend of approximately 90% copper and 10% nickel, with small additions of iron and manganese for enhanced performance. This composition gives the forgings exceptional resistance to corrosion, especially in aggressive saltwater environments. Mechanically, they are known for their excellent tensile strength and good ductility, allowing them to withstand high pressures and mechanical stress without sacrificing their structural integrity over long periods.

Copper Nickel 90/10 forgings may face challenges like higher cost, susceptibility to galvanic corrosion in specific environments, and limited availability in some sizes, requiring precise processing and material sourcing.
Common welding processes compatible with Copper Nickel 90/10 forgings include TIG (GTAW), MIG (GMAW), and SMAW. Proper filler materials, such as CuNi rods, ensure strong, corrosion-resistant welds for optimal performance.
Durability of Copper Nickel 90/10 forgings is ensured by factors like corrosion resistance, proper heat treatment, precise manufacturing, adequate welding techniques, and protection against galvanic corrosion in marine and industrial environments.
The inherent strength and corrosion-fighting nature of these forgings make them indispensable in marine engineering, where they are commonly used for critical components like pump shafts, valve bodies, and fittings on ships and offshore platforms. Beyond the sea, they are vital in the chemical and petrochemical industries for handling corrosive fluids, and in power plants for condenser tubes and other essential parts. Essentially, wherever equipment faces a constant battle against wear and seawater, you’ll find the durable reliability of Copper Nickel 9010 forgings at work.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
